Abrégé

A method of filtering a main fluid using a rotary fluid filter. A 360 degree filtration cycle is initiated by receiving, at an initial position, a first portion of a main fluid at a front end of a first fluid flow passage extending through a filter body rotationally mounted within a housing. The filter body is rotated in a rotation direction and the first portion of the main fluid is discharged from a rear end of the first fluid flow passage, having passed through a filter received in the first fluid flow passage. The filter body is rotated further in the rotation direction and a first portion of a backwash fluid is received through the first fluid flow passage from the rear end to the front end. The rotational cycle is completed by rotating the filter body back to the initial position.
